Codex by OpenAI
Launching today
Introducing the Codex app for macOS—a command center for AI coding and software development with multiple agents, parallel workflows, and long-running tasks.
The Codex app changes how software gets built and who can build it—from pairing with a single coding agent on targeted edits to supervising coordinated teams of agents across the full lifecycle of designing, building, shipping, and maintaining software.

Interesting stuff!
Cool to see OpenAI coming up with new alternatives - looking forward to testing it out
The worktrees feature is the sleeper hit here. Most developer workflows break down when you need context switching - you're mid-refactor on one branch, but a critical bug comes in. With isolated worktrees, you can spin up a separate agent instance without losing state on your current work.
The skills architecture is also smart. Rather than trying to make Codex do everything natively, connecting to Vercel/Figma/Linear means the agent can actually complete end-to-end workflows. Deploy, then open a PR, then update the Linear ticket - without leaving the context window.
Curious about failure handling though - when an automation runs overnight and hits an edge case, what's the recovery flow? Does it queue for human review or attempt self-correction first?
Good job! Has someone done a thoughtful comparison with Claude Code?
